Uno objoot of the invention is to provide :i Spark plug holder oi' novel construction that is iidiip'ted) tolio applied which ore .not equipped with, n priming cup. And :another ohiect is to provide zi combined spark plug holder and priming ciip which can ho ilo-ed with various kinds of spark plugs. 4 I

A duct 6 is foi-mod in the musing 3' and iii the discharge noir/doet thm-oon, :is shown-in Fig. 2, sind a. loot (lo is formed in the valve 7 whichis ro tntnflily mounted in tho casing 3 so ns to per.. init tho fiiel in the cup 5 to ow into the cylndor when the volvo is adjusted in the posi: tion Shown in Fig.

A spring 8, which is arranged on the stem 7* of the vulve between tho :using 3 und u stop ,7 on said stem, holds tho valve sented, and a handle 9 is fastened to one end of the valve stom for enabling I sume to he turned easily so as to stop nrty the flow'o fuel into the cylinder. By referring to Fig. EZ it will'` be seen that'tho horizontal .shelf 'or lodge 2 which lies filiglilty below the fuel duct. 6 receives and rotiiins n hn of fuel in close proximity" to' tho iring'hins ol tho spark plug, thus aiding iii the iimition of the charge.

'le deoirod to equi mi. engine with o priming viii, tho spark p iig can be removed from ihr o vliiider :md tho device above doseril'iod oon he fscrowod into the opening from whioi'i the spiirk plug was removed, the spark plug lining thereafter mounted in the cyliiidiiezil-sli`imed portion 2 of the device.

Any oi thownrioini typos of spark plugs now on thoy market can oe used with the device rio thany the owner is not limited or restricted to :my particular make of spark plug' and :r2 tho device' is mounted in the iisinil spin lc plug oponmgin the o ylinder, no oxpoiiso is involved in applying the devine to :iii engine.

'The 'features coiirso tl le most rire, hut niioiher desizible feature is that the contacts of the Spark plug mounted in tho device uro not apt to become covered with soot and dirt. owiii to the fact that the eyl'iiidricnl-shnped portion 2 which receives the spurl: plug is arranged out-sideof the cylinder of the engine instead of directly in- :saido of stime.
